20 Most Recent Yamaha RXV667 Receiver Questions & Answers

Could be a faulty hdmi cable...

Yes you can but you must set your receiver for 6 ohms I’m happy to help further over the phone at https://www.6ya.com/expert/glenn_3b3dd885737c06f6

Put in a cd and hit play

If it does not light up at all it is probably the power fuse right on the AC line. If it lights up with no sound it is probably a speaker protection fuse or breaker. Unlike some older equipment the fuse is not accessible without opening up the unit.

Looks like an online firmware update failed, mine did the same. Go to the Yamaha download page download the latest firmware to a USB stick and follow the instructions to run the upgrade from there.

I presume that your amplifier is not working after the impedance was changed. If the speaker connections had shorted while this was changed with the power ON then it is possible that the amplifier had encountered a fault with a higher current drain which had triggered it to a protection fault condition. The fault can be with your output drivers. Please check for short on the outputs fitted for both the channels. Use a meter after disconnecting to check for short in the drivers. Disconnect the positive and negative voltages to the output and see if the protect changes. Even a fault in the preamp stages that drives in high current into the output can shut the Amplifier. Sometimes this can be a noise which can be a HUM or HISS before the protect works. Faulty capacitors in these circuits also can cause similar issues and needs close observation.You need to confirm and replace the specific stages or outputs. If not there can be issues in the mother board. Maybe the protect circuit by itself is shutting off due to a faulty bias or there is a leak in any voltage/current sensing circuit. Also disconnect the speakers and test, if the amplifier comes out of the protect mode then check for short on the speakers.

• Hi, talked to the customer. Good conversation. These new Yamaha receivers once in protect mode have to be sent back to Yamaha. Customer already unplugged it for a few minutes and tried another outlet to no avail. The old days or hitting a switch or replacing a fuse are gone for these. Yamaha has now gone to an interface that brings the receiver back to life again and unless you have it you can't do anything with it. Yamaha is the only ones who can bring the receiver out of protect. It's unfortunate but it is the way it is with these new Yamaha receivers.

• Good luck to you.

Have you checked the input souce under the OSD menu? I imagine you did. If so make sure the Speaker selector is pointing to A only and Bi-Amp is Disable. Let me know! it it works Good Luck.

Yes, refer to the manuals for each then ask about specific parts you can't work out.

Here's one...

Consider the TV's role in all of this and it may nake things easier.

A TV's speakers are NOT generally considered a viable additions or alternatives to audio-specific designs. That is not to say they aren't better than some. Just that same TV's usually are not at the output end of an audio chain for good reason. Video, yes.

Even though this may go 'against the book', I'd recommend you go for minimal receiver involvement in the video side other than to send composite video to the TV from "Monitor Out" so you can set up and manage the receiver through the TV.

You can also send Cable- or Sat Box basic analog audio directly to the TV if it has inputs for audio. That way if you just want to watch the news or weather you don't need to fire up the Receiver.

Your video sources (DVD, BD, Cable/Sat) can suffer fewer video anomalies and unnecessary modifications or conversions if you send their BEST video directly to the TV and their BEST audio directly to the receiver. That way everything is handled only once by the best electronics you have for each function.

Hello
Get into Yamaha website www.yamaha.com/service where you can see the option for registering your device. OK.

The problem must be with the Amp's video processor. Did you try using both the HDMI cables one by one directly form the PS3 to the TV and confirm if its not a cable problem.
Next try switching the PS3 video output to 720p or 1080i. if the picture is ok your Yamaha is have having problems processing Full HD signals.Was it OK before or you are trying this out for the first time. More on reply.
